I think if they are going to have a team event, then they need to allow all countries to have skaters in each of the 4 disciplines regardless of if they qualified in the individual events or not. So Japan would get to send a team to compete in Dance for the team event, but since a dance team did not qualify for the individual event then that Dance team would compete ONLY in the team event.

It just doesn't make sense to me to allow a country to compete with skaters in only 3 of the disciplines. That would be like a gymnastics team not competing on one of the apparatus...

BravesSkateFan, they are allowed to bring in one skater/couple that didn't qualify. Japan's pair and Britain's man are only competing in the team event. (Japan's dance team qualified at Nebelhorn.)

Japan's pair is going to compete in the regular event barring a last minute turnaround by Estonia on Alexandr Zaboev's citizenship. Takahashi/Kihara were the first alternates via Nebelhorn placements, so they get the vacated spot.

I thought I had read that some countries would only be fielding a team in 3 of the 4 discipline. Perhaps I misread it.

Countries must participate in 3 of the 4 disciplines to participate in the team event, BUT are allowed to add an additional skater/couple as per the rules just for the team event through the Additional Athletes Quota. I believe the assumption is that countries that only qualified 2 disciplines are therefore still eligible to the team event if they can add an additional athlete for the requisite 3 disciplines.
